Convert characters to Unicode
This tool will convert Chinese, Japanese (hiragana, katakana, and kanji), tonal Hanyu Pinyin, Cyrillic (and just about everything else) into the decimal (not hex) form of Unicode numerical character references (NCRs).
These NCRs can then be used in Web pages, with greater ease than for example the Chinese characters themselves for those whose operating systems or other software don't handle double-byte text well.
For example "слово" can also be written as "слово".
Remember: for this to work, the "charset" of the Web page should be set to Unicode:
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
